Abstract
The invention discloses a series voltage stabilizing circuit which comprises an operational amplifier, a resistor, a capacitor, an inductor and a diode. The series voltage stabilizing circuit converts alternating currents into pulsant direct currents through the unilateral conductivity of the diode to restrain the ripple waves in the output direct current voltages. The series voltage stabilizing circuit is especially suitable for being used in small-power power supply systems, saves energy, and stabilizes the output voltages by controlling the ratio of the connecting time and disconnecting time of a regulating tube, and the stabilizing effect is better.
